Granite
Natural stones are categorized into three groups known
as igneous, metamorphic, and sedimentary rocks.
Granite falls into a group of igneous rocks, which are
compromised of about 45-66% of quartz making it hard
and durable in nature – perfect choice for kitchen
countertops.
Other minerals that make up igneous rocks are feldspar,
mica and iron ores.
Granite is derived from quarries that are located
at the rock beds formed over millions of years from
the some of the same minerals that formed the body
of Earth. At one time those minerals were hot
but as they cooled down they condensed to a solid
core forming the Earth.
In the formation process, as the Earth's crust was
developing through pressure it began pushing
heavy minerals down to the core of the Earth.
The crust grew thicker and squeezed around the
inner core of the Earth creating intense pressure
and heat, resulting in the release of mineral
vapors. These vapors in turn caused crystals
and other solid forms to grow. With the expansion
of crust, these solid minerals were forced up
to the Earth's surface. Thus were formed these
same rock beds that are now used as quarries
for granite. Granite is the most abundant igneous
rock found on earth.
At the quarries, the stone is cut into huge blocks,
and then into required thickness, usually with one
surface honed or polished. Tiles and panels are cut
to size in factories, and then packed for further shipment
to stone retailers all over the world.
Natural stones such as marble and granite come from
quarries found all over the world. Some of the most popular
stones come from such countries as Italy, Spain, Turkey,
United States, Mexico, China, Taiwan, India, Greece,
Canada, France, and Brazil.
